  1. 1. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hjörtur Brynjarsson; [2021]
    Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  2. 2. Techno-economic assessment of CO2 refrigeration systems with geothermal integration : a field measurements and modelling analysis

    University essay from KTH/Energisystem

    Author : Fabio Giunta; [2020]
    Keywords : CO2 Refrigeration; Supermarkets; Heat Recovery; Geothermal Storage; Energy Efficiency; Boreholes; Techno-Economic Assessment;

    Abstract : Several CO2 transcritical booster systems in supermarkets use the potential of integrating geothermal storage, enabling subcooling during warm climate conditions as well as being a heat source during cold climate conditions. First of all, field measurements of one of these systems located in Sweden were analysed with particular focus on the heat-recovery performance. READ MORE

  3. 3. Feasibility study for a 300kW pilot scale hydrogen production process from wood biomass : The case of Sandviksverket, Växjö

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Derick Samjeila Ewang; [2020]
    Keywords : Hydrogen; Biomass; Pyrolysis; Gasification; Combustion.;

    Abstract : Historically, fossil fuel sources (coal, oil and natural gas) have played significant role in meet global energy demand. As global population continue to rise, more and more energy resources are needed and there is a continuous depletion of these energy resources. READ MORE

  4. 4. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : DIYUE WANG; [2020]
    Keywords : Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Abstract : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

  5. 5. Modeling of a stand-alone liquid air energy storage

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fabian Andersson; [2020]
    Keywords : Technology and Engineering;

    Abstract : The aim of this project was to create a model of the stand-alone LAES for use in future work at Siemens Industrial Turbomachinery (SIT). The model was created in IPSEpro with components developed from the software's standard library of power plant components. Required fluid properties were obtained from the Refprop DLL. READ MORE
